Hi Lucy, thank you for asking. Access is available only to registered overnight guests of the resort.
Some require a wristband which you get when checking in. Be sure to speak with front desk because there is a towel girl there on a power trip lol
I don't see why not, I visited a friend who was staying at a Hyatt back on Philadelphia and had no issues with the same situation. However, I would suggest speaking to the front desk on that one, just to be sure.
Thanks! Your answer is awaiting moderation.
